A spectacular blast on Mount St Helens last night

It seems as if a large part of the large "spine" that was growing out of the lavadome collapsed last night in a spectacular blast of activity. Processed images from the Volcanocam (see above) clear show a large amount of bright (i.e. hot!) material being ejected from the area around the lavadome. I have just posted an animation of the event here.

The large tremor associated with the event can be clearly seen just after 22:50 in the webicorder trace below.
